How to perform a blood transfusion on a dog? - briefly

To perform a blood transfusion on a dog, start by ensuring that the donor and recipient dogs are compatible in terms of blood type (DEA 1.1 positive or negative) and cross-matching their blood samples. Then, administer the transfusion slowly over a period of 4 to 6 hours, monitoring the dog for any adverse reactions throughout the process.

How to perform a blood transfusion on a dog? - in detail

Performing a blood transfusion on a dog is a critical procedure that requires meticulous planning, attention to detail, and adherence to best practices to ensure safety and efficacy. Here's a comprehensive guide on how to perform this procedure:

Preparation

1. Assessment: Begin by thoroughly assessing the dog’s condition. Determine the type of blood needed (whole blood, packed red blood cells, plasma) based on the diagnosis and clinical signs.
2. Donor Selection: Choose a healthy donor dog that is free from infectious diseases such as babesiosis, ehrlichiosis, or leishmaniasis. The donor should be of similar size to the recipient to minimize the risk of transfusion reactions.
3. Blood Collection: Use sterile equipment for blood collection. Insert a catheter into the donor’s jugular vein and collect the required amount of blood in a bag containing citrate-phosphate-dextrose-adenine (CPDA) solution to prevent clotting.
4. Cross-Matching: Perform cross-matching between the donor and recipient blood to ensure compatibility. This step helps avoid adverse reactions such as hemolysis.
5. Pre-Transfusion Testing: Conduct a complete blood count (CBC) and biochemical profile on the donor blood to confirm its safety for transfusion.

Transfusion Procedure

1. Catheter Placement: Insert an intravenous catheter into the recipient dog’s cephalic or jugular vein. Use aseptic technique to prevent infection.
2. Initial Dose: Administer a small amount of blood (5-10 mL) initially to monitor for any adverse reactions. Observe the dog closely for signs such as tachycardia, hypersalivation, or hives.
3. Slow Infusion: If no reaction occurs, start the transfusion slowly at a rate of 2-4 mL/kg/hour. Use an infusion pump to maintain a consistent flow rate.
4. Monitoring: Continuously monitor the recipient dog’s vital signs throughout the transfusion. Keep track of heart rate, respiratory rate, temperature, and blood pressure.
5. Duration: The duration of the transfusion depends on the amount of blood needed and the dog's condition. Typically, a transfusion can take 2-4 hours.
6. Completion: Once the required volume is administered, flush the catheter with saline to prevent clotting. Remove the catheter carefully and apply pressure to the site to stop any bleeding.

Post-Transfusion Care

1. Monitoring: Continue monitoring the dog’s vital signs for at least 24 hours post-transfusion. Look for signs of delayed transfusion reactions.
2. Hydration: Ensure the recipient is well-hydrated to support the increased blood volume and prevent complications such as hemolysis or clotting.
3. Follow-Up: Perform follow-up tests, including CBC and biochemical profile, to evaluate the effectiveness of the transfusion and monitor for any complications.
4. Record Keeping: Maintain detailed records of the transfusion procedure, including the amount of blood administered, donor information, and recipient’s response. This information is crucial for future reference and follow-up care.

Complications and Management

1. Transfusion Reactions: Be prepared to manage transfusion reactions such as fever, tachycardia, hypersalivation, or anaphylaxis. Have appropriate medications (e.g., antihistamines, corticosteroids) on hand.
2. Hemolysis: Monitor for signs of hemolysis, including dark urine, jaundice, and anemia. Manage with supportive care and hydration.
3. Infections: Be aware of the risk of transmitting infectious diseases. Ensure that donor blood is screened for common pathogens before transfusion.

By adhering to these detailed steps, veterinary professionals can safely and effectively perform a blood transfusion on a dog, ensuring optimal outcomes and minimizing risks.
